Book Description
The southern Black Warrior Basin has been the site of limited drilling operations, but a critical need existed for a greater understanding of the regional stratigraphy. The objectives of this study were to define a sequence stratigraphic framework for the southernmost Black Warrior Basin, to identify chronostratigraphic timelines within depositional environments, identify regional transgressive and regressive cycles. This information was used to identify three target reservoirs, characterize petrophysical properties, and confirm integrity of reservoir and seal formations for geologic storage. Methods included correlation of petrophysical well logs in the study area, petrographic well log analysis, and core analyses. Five cycles were identified in well log cross sections. Sequence boundaries were identified in cross sections and tied to seismic data. Cretaceous sediments deposited above a Paleozoic sequence boundary that may represent ~141 ma of erosion or non-deposition. These results contributed to development of a proposed geologic carbon sequestration facility in Mississippi.
